Abstract
Immediate and long-term mechanisms interact in the regulation of action. We will examine neurobiology and practical clinical consequences of these interactions. Long-term regulation of immediate behavioural control is based on analogous responses to highly rewarding or stressful stimuli: (i) impulsivity is a failure of the balance between activation and inhibition in the immediate regulation of action. (ii) Sensitization is a persistently exaggerated behavioural or physiological response to highly salient stimuli, such as addictive stimuli or inescapable stress. Sensitization can generalize across classes of stimuli. (iii) Impulsivity, possibly related to poor modulation of catecholaminergic and glutamatergic functions, may facilitate development of long-term sensitized responses to stressful or addictive stimuli. In turn, impulsivity is prominent in sensitized behaviour. (iv) While impulsivity and sensitization are general components of behaviour, their interactions are prominent in the course of bipolar disorder, emphasizing roles of substance-use, recurrent course and stressors. (v) Suicide is a complex and severe behaviour that exemplifies the manner in which impulsivity facilitates behavioural sensitization and is, in turn, increased by it, leading to inherently unpredictable behaviour. (vi) Interactions between impulsivity and sensitization can provide targets for complementary preventive and treatment strategies for severe immediate and long-term behavioural disorders. Progress along these lines will be facilitated by predictors of susceptibility to behavioural sensitization. This article is part of the theme issue 'Risk taking and impulsive behaviour: fundamental discoveries, theoretical perspectives and clinical implications'.

Abstract
Purpose Interdisciplinary bedside ward rounds have the capacity to facilitate coordinated interprofessional patient care. To be an effective means of care coordination, clinicians need an explicit understanding of how these rounds contribute to patient care. By identifying benefits and challenges to the effective use of interdisciplinary ward rounds, clinicians create an opportunity to improve interprofessional teamwork, care planning, and coordination of patient care. Methods A survey was conducted with frontline professionals in two acute care and two rehabilitation wards from a metropolitan teaching hospital. There were 77 participants, representing medical officers, nurses, and allied health clinicians. Questions examined the perceived benefits and challenges of conducting interdisciplinary ward rounds in their units. Survey findings were coded for meaning and then grouped into themes. Results Benefits revealed a desired care delivery model challenged by the complexities of organizational and professional cultures. The themes of “being on the same page”, “focusing on patients”, and “holistic care planning” underpinned the ideas of collaboration and improved patient-centred care, that is, benefits to patients. Challenges centred on health professionals' time constraints and the coordination of teams to enable participation in rounds. The themes were more distinct, logistical barriers of “time”, “workforce”, and “care planning”. Conclusion Overall, clinicians recognise there are greater benefits to IBRs and have a willingness to participate. However, careful consideration is required to introduce and continually achieve the best from IBR as they require changes in organizational context and culture.

Abstract
Patients with atrial fibrillation (AF) who suffer an acute ischemic stroke are at risk for both hemorrhagic transformation and recurrent ischemic stroke in the acute post-stroke period. Oral anticoagulants are recommended for secondary stroke prevention in patients with AF. The optimal time to initiate anticoagulant therapy after acute ischemic stroke in patients with AF is uncertain. There is concern that early initiation increases the risk of hemorrhagic transformation, whereas delayed initiation leaves the patient at risk for recurrent ischemic stroke. In this article, we provide a review of the risk of hemorrhagic transformation of acute ischemic stroke as well as review the literature and major guidelines addressing the timing of anticoagulation initiation after an acute ischemic stroke in patients with AF. Relevant articles published from 1990 to the present were identified using the PubMed and Embase databases. The majority of available literature is observational data. Large ischemic lesions, cerebral microbleeds, thrombolytic therapy, and other clinical factors may increase the risk of hemorrhagic transformation of an acute ischemic stroke. Parenteral anticoagulation within 48 hours is associated with an increased risk of hemorrhagic transformation and is not recommended. Insufficient data exist to support the safety of routine oral anticoagulant (direct oral anticoagulants or warfarin) initiation within 48 hours of an acute ischemic stroke. Direct oral anticoagulant initiation within 2 days of an acute ischemic stroke is associated with a 5% rate of hemorrhagic transformation. Infarct size and presence of hemorrhage are important factors in identifying the optimal time to initiation and should guide decisions when available. A recommended framework for patient decision making is provided. Randomized controlled trials in this area are needed to identify the optimal timing of anticoagulation initiation, and such trials are under way.

Abstract
Background: Despite recent advances in acute stroke care, only 1–8% of patients can receive reperfusion therapies, mainly because of prehospital delay (PHD). Objective: This study aimed to identify factors associated with PHD from the onset of acute stroke symptoms until arrival at the hospital. Methods: A cross-sectional study was conducted including all patients consecutively admitted with stroke symptoms to Burgos University Hospital (Burgos, Spain). Socio-demographic, clinical, behavioral, cognitive, and contextualized characteristics were recorded, and their possible associations with PHD were studied using univariate and multivariable regression analyses. Results: The median PHD of 322 patients was 138.50 min. The following factors decreased the PHD and time until reperfusion treatment where applicable: asking for help immediately after the onset of symptoms (OR 10.36; 95% confidence interval (CI) 4.47–23.99), onset of stroke during the daytime (OR 7.73; 95% CI 3.09–19.34) and the weekend (OR 2.64; 95% CI 1.19–5.85), occurrence of stroke outside the home (OR 7.09; 95% CI 1.97–25.55), using a prenotification system (OR 6.46; 95% CI 1.71–8.39), patient’s perception of being unable to control symptoms without assistance (OR 5.14; 95% CI 2.60–10.16), previous knowledge of stroke as a medical emergency (OR 3.20; 95% CI 1.38–7.40), call to emergency medical services as the first medical contact (OR 2.77; 95% CI 1.32–5.88), speech/language difficulties experienced by the patient (OR 2.21; 95% CI 1.16–4.36), and the identification of stroke symptoms by the patient (OR 1.98; 95% CI 1.03–3.82). Conclusions: The interval between the onset of symptoms and arrival at the hospital depends on certain contextual, cognitive, and behavioral factors, all of which should be considered when planning future public awareness campaigns.

Abstract
Background Lung cancer is the number one cause of cancer death in America. Timely and appropriate care is critical in the management of lung cancer. We retrospectively reviewed our experience at the University of Kentucky to determine whether there were delays from initial presentation to diagnosis and from diagnosis to treatment. Furthermore, if delays existed, whether they affected overall survival and what factors contributed to these holdups in patient care. Methods This was a retrospective review of all patients who were diagnosed with lung cancer at the University of Kentucky between 2014 and 2017, including only those newly diagnosed at our institution and excluding patients who were diagnosed at other hospitals as well as patients with cancer recurrence. Out of a cohort of 3588 patients, only 517 were included. Results The average time between presentation and diagnosis was 43 days, and 86.7% of patients were diagnosed within 60 days. The average time to treatment from diagnosis was 27.5 days with 77.7% of patients being treated with either surgery, chemotherapy, and/or radiation within 42 days. Conclusion The majority of our patients were diagnosed and treated within the recommended time. The 13.3% and 22.3% of patients who did not fall within this timeframe were delayed due to personal reasons, comorbidities, and/or “watchful waiting”. Mortality seemed to be unaffected by any delays in diagnosis or treatment. This analysis is the first step in understanding the challenges in patient care, and can be a tool to institute programs to help patients obtain necessary care.

Abstract
BACKGROUND Infants born preterm (before 37 weeks' gestation) have poorer outcomes than infants at term, particularly if born before 32 weeks. Early cord clamping has been standard practice over many years, and enables quick transfer of the infant to neonatal care. Delayed clamping allows blood flow between the placenta, umbilical cord and baby to continue, and may aid transition. Keeping baby at the mother's side enables neonatal care with the cord intact and this, along with delayed clamping, may improve outcomes. Umbilical cord milking (UCM) is proposed for increasing placental transfusion when immediate care for the preterm baby is needed. This Cochrane Review is a further update of a review first published in 2004 and updated in 2012. OBJECTIVES To assess the effects on infants born at less than 37 weeks' gestation, and their mothers of: 1) delayed cord clamping (DCC) compared with early cord clamping (ECC) both with immediate neonatal care after cord clamping; 2) DCC with immediate neonatal care with cord intact compared with ECC with immediate neonatal care after cord clamping; 3) DCC with immediate neonatal care after cord clamping compared with UCM; 4) UCM compared with ECC with immediate neonatal care after cord clamping. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (10 November 2017), and reference lists of retrieved studies. We updated the search in November 2018 and added nine new trial reports to the awaiting classification section to be assessed at the next update. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing delayed with early clamping of the umbilical cord (with immediate neonatal care after cord clamping or with cord intact) and UCM for births before 37 weeks' gestation. Quasi-RCTs were excluded. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Random-effects are used in all meta-analyses. Review authors assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS This update includes forty-eight studies, involving 5721 babies and their mothers, with data available from 40 studies involving 4884 babies and their mothers. Babies were between 24 and 36+6 weeks' gestation at birth and multiple births were included. The data are mostly from high-income countries. Delayed clamping ranged between 30 to 180 seconds, with most studies delaying for 30 to 60 seconds. Early clamping was less than 30 seconds and often immediate. UCM was mostly before cord clamping but some were milked after cord clamping. We undertook subgroup analysis by gestation and type of intervention, and sensitivity analyses by low risk of selection and attrition bias.All studies were high risk for performance bias and many were unclear for other aspects of risk of bias. Certainty of the evidence using GRADE was mostly low, mainly due to imprecision and unclear risk of bias.Delayed cord clamping (DCC) versus early cord clamping (ECC) both with immediate neonatal care after cord clamping (25 studies, 3100 babies and their mothers)DCC probably reduces the number of babies who die before discharge compared with ECC (average risk ratio (aRR) 0.73, 95% confidence interval (CI) 0.54 to 0.98, 20 studies, 2680 babies (moderate certainty)).No studies reported on 'Death or neurodevelopmental impairment' in the early years'.DCC may make little or no difference to the number of babies with severe intraventricular haemorrhage (IVH grades 3 and 4) (aRR 0.94, 95% CI 0.63 to 1.39, 10 studies, 2058 babies, low certainty) but slightly reduces the number of babies with any grade IVH (aRR 0.83, 95% CI 0.70 to 0.99, 15 studies, 2333 babies, high certainty).DCC has little or no effect on chronic lung disease (CLD) (aRR 1.04, 95% CI 0.94 to 1.14, 6 studies, 1644 babies, high certainty).Due to insufficient data, we were unable to form conclusions regarding periventricular leukomalacia (PVL) (aRR 0.58, 95% CI 0.26 to 1.30, 4 studies, 1544 babies, low certainty) or maternal blood loss of 500 mL or greater (aRR 1.14, 95% CI 0.07 to 17.63, 2 studies, 180 women, very low certainty).We identified no important heterogeneity in subgroup or sensitivity analyses.Delayed cord clamping (DCC) with immediate neonatal care with cord intact versus early cord clamping (ECC) (one study, 276 babies and their mothers)There are insufficient data to be confident in our findings, but DCC with immediate neonatal care with cord intact may reduce the number of babies who die before discharge, although the data are also compatible with a slight increase in mortality, compared with ECC (aRR 0.47, 95% CI 0.20 to 1.11, 1 study, 270 babies, low certainty). DCC may also reduce the number of babies who die or have neurodevelopmental impairment in early years (aRR 0.61, 95% CI 0.39 to 0.96, 1 study, 218 babies, low certainty). There may be little or no difference in: severe IVH; all grades IVH; PVL; CLD; maternal blood loss ≥ 500 mL, assessed as low certainty mainly due to serious imprecision.Delayed cord clamping (DCC) with immediate neonatal care after cord clamping versus umbilical cord milking (UCM) (three studies, 322 babies and their mothers) and UCM versus early cord clamping (ECC) (11 studies, 1183 babies and their mothers)There are insufficient data for reliable conclusions about the comparative effects of UCM compared with delayed or early clamping (mostly low or very low certainty). AUTHORS' CONCLUSIONS Delayed, rather than early, cord clamping may reduce the risk of death before discharge for babies born preterm. There is insufficient evidence to show what duration of delay is best, one or several minutes, and therefore the optimum time to clamp the umbilical cord remains unclear. Whilst the current evidence supports not clamping the cord before 30 seconds at preterm births, future trials could compare different lengths of delay. Immediate neonatal care with the cord intact requires further study, and there are insufficient data on UCM.The nine new reports awaiting further classification may alter the conclusions of the review once assessed.

Abstract
PURPOSE Self-reported measurement tools often provide a recall period, eg "In the past 7 days…" For lower urinary tract symptoms the concordance of end of day (daily) reports with 7 and 30-day recalled reports is unknown to our knowledge. We evaluated how accurately 7 or 30-day recall questions capture lower urinary tract symptoms. MATERIALS AND METHODS The 261 female and 254 male participants were recruited from a total of 6 United States tertiary care sites. We evaluated 18 items representing 7 symptoms covering storage, voiding and post-micturition symptoms. Item responses on the daily forms were averaged for a 7 or a 30-day period and compared to the corresponding 7 or 30-day recall version of the item. Analyses were item and gender specific. Within person concordance was assessed using the Pearson correlation. Bias (systematic overreporting or underreporting) was calculated as the difference between the recalled item and the averaged daily item score, and reported as a percent of the item scale. RESULTS All correlations exceeded 0.60. Correlations between averaged daily reports and recalled reports ranged from 0.72 to 0.89 for 7 days and from 0.71 to 0.91 for 30 days among women, and from 0.68 to 0.90 and 0.68 to 0.95, respectively, among men. Most items did not show systematic bias and the median percent bias did not exceed 10% for any item. However, bias exceeding ±10% for some items was observed in a subset of individuals. CONCLUSIONS Recalled reports during the 7 and 30 days tracked well with averaged daily reports for men and women. Systematic bias was minimal, suggesting that 7 and 30-day recall periods for self-reported lower urinary tract symptoms are reasonable.

Abstract
BACKGROUND AND OBJECTIVES The burden of infectious disease is high among kidney transplant recipients because of concomitant immunosuppression. In this study the incidence of infectious-related mortality and associated factors were evaluated. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS In this registry-based retrospective, longitudinal cohort study, recipients of a first kidney transplant in Australia and New Zealand between 1997 and 2015 were included. Cumulative incidence of infectious-related mortality was estimated using competing risk regression (using noninfectious mortality as a competing risk event), and compared with age-matched, populated-based data using standardized incidence ratios. RESULTS Among 12,519 patients, (median age 46 years, 63% men, 15% diabetic, 6% Indigenous ethnicity), 2197 (18%) died, of whom 416 (19%) died from infection. The incidence of infection-related mortality during the study period (1997-2015) was 45.8 (95% confidence interval [95% CI], 41.6 to 50.4) per 10,000 patient-years. The incidence of infection-related mortality reduced from 53.1 (95% CI, 45.0 to 62.5) per 10,000 person-years in 1997-2000 to 43.9 (95% CI, 32.5 to 59.1) per 10,000 person-years in 2011-2015 (P<0.001) Compared with the age-matched general population, kidney transplant recipients had a markedly higher risk of infectious-related death (standardized incidence ratio, 7.8; 95% CI, 7.1 to 8.6). Infectious mortality was associated with older age (≥60 years adjusted subdistribution hazard ratio [SHR], 4.16; 95% CI, 2.15 to 8.05; reference 20-30 years), female sex (SHR, 1.62; 95% CI, 1.19 to 2.29), Indigenous ethnicity (SHR, 2.87; 95% CI, 1.84 to 4.46; reference white), earlier transplant era (2011-2015: SHR, 0.39; 95% CI, 0.20 to 0.76; reference 1997-2000), and use of T cell-depleting therapy (SHR, 2.43; 95% CI, 1.36 to 4.33). Live donor transplantation was associated with lower risk of infection-related mortality (SHR, 0.53; 95% CI, 0.37 to 0.76). CONCLUSIONS Infection-related mortality in kidney transplant recipients is significantly higher than the general population, but has reduced over time. Risk factors include older age, female sex, Indigenous ethnicity, T cell-depleting therapy, and deceased donor transplantation.

Abstract
BACKGROUND The prevention of long-term psychological distress following traumatic events is a major concern. Systematic reviews have suggested that individual psychological debriefing is not an effective intervention at preventing post-traumatic stress disorder (PTSD). Over the past 20 years, other forms of intervention have been developed with the aim of preventing PTSD. OBJECTIVES To examine the efficacy of psychological interventions aimed at preventing PTSD in individuals exposed to a traumatic event but not identified as experiencing any specific psychological difficulties, in comparison with control conditions (e.g. usual care, waiting list and no treatment) and other psychological interventions. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PsycINFO and ProQuest's Published International Literature On Traumatic Stress (PILOTS) database to 3 March 2018. An earlier search of CENTRAL and the Ovid databases was conducted via the Cochrane Common Mental Disorders Controlled Trial Register (CCMD-CTR) (all years to May 2016). We handsearched reference lists of relevant guidelines, systematic reviews and included study reports. Identified studies were shared with key experts in the field.We conducted an update search (15 March 2019) and placed any new trials in the 'awaiting classification' section. These will be incorporated into the next version of this review, as appropriate. SELECTION CRITERIA We searched for randomised controlled trials of any multiple session (two or more sessions) early psychological intervention or treatment designed to prevent symptoms of PTSD. We excluded single session individual/group psychological interventions. Comparator interventions included waiting list/usual care and active control condition. We included studies of adults who experienced a traumatic event which met the criterion A1 according to the Diagnostic and Statistical Manual (DSM-IV) for PTSD. DATA COLLECTION AND ANALYSIS We entered data into Review Manager 5 software. We analysed categorical outcomes as risk ratios (RRs), and continuous outcomes as mean differences (MD) or standardised mean differences (SMDs), with 95% confidence intervals (CI). We pooled data with a fixed-effect meta-analysis, except where there was heterogeneity, in which case we used a random-effects model. Two review authors independently assessed the included studies for risk of bias and discussed any conflicts with a third review author. MAIN RESULTS This is an update of a previous review.We included 27 studies with 3963 participants. The meta-analysis included 21 studies of 2721 participants. Seventeen studies compared multiple session early psychological intervention versus treatment as usual and four studies compared a multiple session early psychological intervention with active control condition.Low-certainty evidence indicated that multiple session early psychological interventions may be more effective than usual care in reducing PTSD diagnosis at three to six months' follow-up (RR 0.62, 95% CI 0.41 to 0.93; I2 = 34%; studies = 5; participants = 758). However, there was no statistically significant difference post-treatment (RR 1.06, 95% CI 0.85 to 1.32; I2 = 0%; studies = 5; participants = 556; very low-certainty evidence) or at seven to 12 months (RR 0.94, 95% CI 0.20 to 4.49; studies = 1; participants = 132; very low-certainty evidence). Meta-analysis indicated that there was no statistical difference in dropouts compared with usual care (RR 1.34, 95% CI 0.91 to 1.95; I2 = 34%; studies = 11; participants = 1154; low-certainty evidence) .At the primary endpoint of three to six months, low-certainty evidence indicated no statistical difference between groups in reducing severity of PTSD (SMD -0.10, 95% CI -0.22 to 0.02; I2 = 34%; studies = 15; participants = 1921), depression (SMD -0.04, 95% CI -0.19 to 0.10; I2 = 6%; studies = 7; participants = 1009) or anxiety symptoms (SMD -0.05, 95% CI -0.19 to 0.10; I2 = 2%; studies = 6; participants = 945).No studies comparing an intervention and active control reported outcomes for PTSD diagnosis. Low-certainty evidence showed that interventions may be associated with a higher dropout rate than active control condition (RR 1.61, 95% CI 1.11 to 2.34; studies = 2; participants = 425). At three to six months, low-certainty evidence indicated no statistical difference between interventions in terms of severity of PTSD symptoms (SMD -0.02, 95% CI -0.31 to 0.26; I2 = 43%; studies = 4; participants = 465), depression (SMD 0.04, 95% CI -0.16 to 0.23; I2 = 0%; studies = 2; participants = 409), anxiety (SMD 0.00, 95% CI -0.19 to 0.19; I2 = 0%; studies = 2; participants = 414) or quality of life (MD -0.03, 95% CI -0.06 to 0.00; studies = 1; participants = 239).None of the included studies reported on adverse events or use of health-related resources. AUTHORS' CONCLUSIONS While the review found some beneficial effects of multiple session early psychological interventions in the prevention of PTSD, the certainty of the evidence was low due to the high risk of bias in the included trials. The clear practice implication of this is that, at present, multiple session interventions aimed at everyone exposed to traumatic events cannot be recommended. There are a number of ongoing studies, demonstrating that this is a fast moving field of research. Future updates of this review will integrate the results of these new studies.

Abstract
Reversible cerebral vasoconstriction syndrome is a rare disorder associated with neurologic symptoms secondary to diffuse cerebral vasospasm. Cardiac involvement in this disease is exceedingly rare. A 50-year-old woman was admitted to our hospital for evaluation of chest pain. During a 3-year period, she had been admitted multiple times because of chest pain and elevated serum cardiac enzymes. Transthoracic echocardiograms showed transient wall-motion abnormalities; however, coronary angiograms revealed no coronary artery disease. At the current admission, she had a thunderclap headache, and cerebral angiograms revealed diffuse cerebral vasoconstriction that improved after verapamil infusion, confirming the diagnosis of reversible cerebral vasoconstriction syndrome. The patient was treated successfully with oral diltiazem and had no recurrence of symptoms. We describe what we think is the first reported case of coronary artery spasm in association with reversible cerebral vasoconstriction syndrome. Future research should be focused on identifying treatment options and defining the mechanisms by which the cerebral and coronary vasculature are affected.

Abstract
Acute aortic dissection can be complicated by malperfusion syndromes, including ischemia of the lower limbs. In some cases, delayed correction of leg ischemia leads to reperfusion injury, potentially resulting in renal failure. We describe the case of a 64-year-old woman who presented with acute aortic dissection manifesting itself as lower-limb ischemia. During and after aortic surgery with cardiopulmonary bypass, the patient developed myonephropathic metabolic syndrome. Hyperkalemia was corrected and acute kidney injury was prevented by infusing large volumes of intravenous fluids and administering human atrial natriuretic peptide. Peripheral bypass surgery was unnecessary. This case suggests that restoring blood flow to an ischemic leg by means of adjunctive perfusion during aortic repair with cardiopulmonary bypass is a viable way to overcome the biochemical instability associated with prolonged ischemia, especially hyperkalemia in the early phase of reperfusion.

Review article: Impact of 12-lead electrocardiography system of care on emergency medical service delays in ST-elevation myocardial infarction: A systematic review and meta-analysis. Emerg Med Australas 2019; 31:702-709. [PMID: 31190379 DOI: 10.1111/1742-6723.13321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2018] [Revised: 03/05/2019] [Accepted: 04/24/2019] [Indexed: 11/30/2022]
Abstract
To assess the impact of prehospital 12-lead electrocardiography (PH ECG) on emergency medical service (EMS) delay in patients with ST-elevation myocardial infarction (STEMI), we systematically searched five online electronic databases, including MEDLINE, Embase, Emcare, Cochrane Library and CINAHL, between 1990 and August 2017. Controlled trials and observational studies comparing EMS time delays with and without PH ECG in STEMI patients were eligible. Two reviewers independently screened studies for eligibility, extracted data and appraised study quality. The primary outcome was the time elapsed between scene arrival and hospital arrival. The secondary outcomes were response time, scene time, transport time and emergency call-to-hospital arrival time. Random effects models were used to pool weighted mean differences in EMS delay. Seven moderate-quality studies (two controlled trials and five observational) involving 81 005 participants were included in the data synthesis. The primary treatment strategy was in-hospital thrombolysis and percutaneous coronary intervention in four and three studies, respectively. PH ECG was associated with a 7.0 min increase in scene arrival-to-hospital arrival time (three studies; n = 80 628; 95% CI 6.7-7.2; I2 = 0.0%) and a 2.9 min increase in scene time (four studies; n = 377; 95% CI 1.2-4.6; I2 = 0.0%). PH ECG had no effect on transport or call-to-hospital intervals, although both measures showed evidence of heterogeneity. In patients with STEMI, PH ECG is associated with a modest increase in EMS delays. Measurement and improvement of EMS system delays may help to expedite treatment for STEMI.

Abstract
Substantial technological advances in mechanical circulatory support have caused a shift in the management of end-stage heart failure. From the 1970s through the 1990s, heterotopic heart transplantation was routinely performed in patients in whom orthotopic transplantation was likely to fail. Heterotopic heart transplantation is now performed less often because modern mechanical circulatory assist devices are routinely used as bridges to orthotopic transplantation; regardless, the operation has helped numerous patients who would not otherwise have received adequate allografts. We describe the case of a man with idiopathic nonischemic cardiomyopathy who, at age 17, was given an ABO- and size-matched heterotopic allograft that was a complete human leukocyte antigen mismatch. The graft functioned normally for 20 years until the patient had a myocardial infarction that necessitated placement of a coronary artery stent. Subsequent treatments involved many interventions, including insertion of an intra-aortic balloon pump, medical therapy for heart failure, implantation of a total artificial heart, and, ultimately, orthotopic transplantation. To our knowledge, our patient is the longest surviving recipient of a heterotopic heart transplant, with a remarkable 25-year graft survival despite poor histocompatibility and an almost complete lack of native heart function. The strategies used for his treatment make him a living case study that can add valuable information to the history of cardiac support.

Abstract
OBJECTIVE To investigate the effect of emergency medical service (EMS) on the prognosis of ischemic stroke patients treated with intravenous thrombolysis. METHODS Clinical data of 2123 ischemic stroke patients treated with intravenous thrombolysis in 70 hospitals in Zhejiang province were retrospectively analyzed. There were 808 patients sent to the hospital by ambulance (EMS group) and 1315 patients by other transportations (non-EMS group). Good outcome was defined as modified Rankin Scale (mRS) ≤ 2 at 3-month. The onset to needle time (ONT), onset to door time (ODT), door to needle time (DNT) and outcome were compared between EMS group and non-EMS group. Binary logistic regression was used to explore the influencing factors for the outcome at 3-month. RESULTS Compared with the non-EMS group, patients in the EMS group were older, with higher baseline National Institute of Health Sroke Scale (NIHSS) score, and had a higher proportion of atrial fibrillation (all P<0.05), but there were no significant differences in ONT, ODT and DNT between two groups (all P>0.05). Binary logistic regression showed that EMS was not independently associated with good outcome (OR=0.856, 95%CI:0.664-1.103, P>0.05). CONCLUSIONS EMS had not improve the outcome of patients receiving intravenous thrombolysis in Zhejiang province.

Abstract
OBJECTIVE To compare the time delay between in-hospital stroke and out-of-hospital stroke patients, and to explore the influence factors for the prognosis of in-hospital stroke patients treated by intravenous thrombolysis. METHODS Clinical data of 3050 patients with ischemic stroke who received intravenous thrombolysis in 71 hospitals in Zhejiang province from June 2017 to September 2018 were analyzed. Differences of time delay including door to imaging time (DIT), imaging to needle time (INT) and door to needle time (DNT) between in-hospital stroke (n=101) and out-of-hospital stroke (n=2949) were observed. The influencing factors for the outcome at 3 month after intravenous thrombolysis in patients with in-hospital stroke were analyzed using binary logistic regression analysis. RESULTS Patients with in-hospital stroke had longer DIT[53.5 (32.0-79.8) min vs. 20.0 (14.0-28.0) min, P<0.01], longer IDT[47.5(27.3-64.0)min vs. 36.0(24.0-53.0)min, P<0.01], and longer DNT[99.0 (70.5-140.5) min vs. 55.0 (41.0-74.0) min, P<0.01], compared with patients with out-of-hospital stroke; patients in comprehensive stroke center had longer DIT[59.5(44.5-83.3) min vs. 37.5(16.5-63.5) min, P<0.01], longer DNT[110.0(77.0-145.0) min vs. 88.0 (53.8-124.3) min, P<0.05], but shorter INT[36.5(23.8-60.3)min vs. 53.5 (34.3-64.8) min, P<0.05], compared with patients in primary stroke center. Age (OR=0.934, 95%CI: 0.882-0.989, P<0.05) and baseline National Institute of Health Stroke Scale score (OR=0.912, 95%CI: 0.855-0.973, P<0.01) were independent risk factors for prognosis of in-hospital stroke patients. CONCLUSIONS In-hospital stroke had longer DIT and DNT than out-of-hospital stroke, which suggests that a more smooth thrombolysis process of in-hospital stroke should be established.

Abstract
BACKGROUND Kidney transplantation is the optimal treatment for end-stage kidney disease. Retrieval, transport and transplant of kidney grafts causes ischaemia reperfusion injury. The current accepted standard is static cold storage (SCS) whereby the kidney is stored on ice after removal from the donor and then removed from the ice box at the time of implantation. However, technology is now available to perfuse or "pump" the kidney during the transport phase or at the recipient centre. This can be done at a variety of temperatures and using different perfusates. The effectiveness of treatment is manifest clinically as delayed graft function (DGF), whereby the kidney fails to produce urine immediately after transplant. OBJECTIVES To compare hypothermic machine perfusion (HMP) and (sub)normothermic machine perfusion (NMP) with standard SCS. SEARCH METHODS We searched the Cochrane Kidney and Transplant Register of Studies to 18 October 2018 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. SELECTION CRITERIA All randomised controlled trials (RCTs) and quasi-RCTs comparing HMP/NMP versus SCS for deceased donor kidney transplantation were eligible for inclusion. All donor types were included (donor after circulatory (DCD) and brainstem death (DBD), standard and extended/expanded criteria donors). Both paired and unpaired studies were eligible for inclusion. DATA COLLECTION AND ANALYSIS The results of the literature search were screened and a standard data extraction form was used to collect data. Both of these steps were performed by two independent authors. Dichotomous outcome results were expressed as risk ratio (RR) with 95% confidence intervals (CI). Continuous scales of measurement were expressed as a mean difference (MD). Random effects models were used for data analysis. The primary outcome was incidence of DGF. Secondary outcomes included: one-year graft survival, incidence of primary non-function (PNF), DGF duration, long term graft survival, economic implications, graft function, patient survival and incidence of acute rejection. MAIN RESULTS No studies reported on NMP, however one ongoing study was identified.Sixteen studies (2266 participants) comparing HMP with SCS were included; 15 studies could be meta-analysed. Fourteen studies reported on requirement for dialysis in the first week post-transplant (DGF incidence); there is high-certainty evidence that HMP reduces the risk of DGF when compared to SCS (RR 0.77; 95% CI 0.67 to 0.90; P = 0.0006). HMP reduces the risk of DGF in kidneys from DCD donors (7 studies, 772 participants: RR 0.75; 95% CI 0.64 to 0.87; P = 0.0002; high certainty evidence), as well as kidneys from DBD donors (4 studies, 971 participants: RR 0.78, 95% CI 0.65 to 0.93; P = 0.006; high certainty evidence). The number of perfusions required to prevent one episode of DGF (number needed to treat, NNT) was 7.26 and 13.60 in DCD and DBD kidneys respectively. Studies performed in the last decade all used the LifePort machine and confirmed that HMP reduces the incidence of DGF in the modern era (5 studies, 1355 participants: RR 0.77, 95% CI 0.66 to 0.91; P = 0.002; high certainty evidence). Reports of economic analysis suggest that HMP can lead to cost savings in both the North American and European settings.Two studies reported HMP also improves graft survival however we were not able to meta-analyse these results. A reduction in incidence of PNF could not be demonstrated. The effect of HMP on our other outcomes (incidence of acute rejection, patient survival, hospital stay, long-term graft function, duration of DGF) remains uncertain. AUTHORS' CONCLUSIONS HMP is superior to SCS in deceased donor kidney transplantation. This is true for both DBD and DCD kidneys, and remains true in the modern era (studies performed in the last decade). As kidneys from DCD donors have a higher overall DGF rate, fewer perfusions are needed to prevent one episode of DGF (7.26 versus 13.60 in DBD kidneys).Further studies looking solely at the impact of HMP on DGF incidence are not required. Follow-up reports detailing long-term graft survival from participants of the studies already included in this review would be an efficient way to generate further long-term graft survival data.Economic analysis, based on the results of this review, would help cement HMP as the standard preservation method in deceased donor kidney transplantation.RCTs investigating (sub)NMP are required.

Abstract
BACKGROUND Normal aging is associated with changes in cognitive function that are non-pathological and are not necessarily indicative of future neurocognitive disease. Low cognitive and brain reserve and limited cognitive stimulation are associated with increased risk of dementia. Emerging evidence now suggests that subtle cognitive changes, detectable years before criteria for mild cognitive impairment are met, may be predictive of future dementia. Important for intervention and reduction in disease risk, research also suggests that engaging in stimulating mental activity throughout adulthood builds cognitive and brain reserve and reduces dementia risk. Therefore, midlife (defined here as 40 to 65 years) may be a suitable time to introduce cognitive interventions for maintaining cognitive function and, in the longer term, possibly preventing or delaying the onset of clinical dementia. OBJECTIVES To evaluate the effects of computerised cognitive training interventions lasting at least 12 weeks for maintaining or improving cognitive function in cognitively healthy people in midlife. SEARCH METHODS We searched up to 31 March 2018 in ALOIS (www.medicine.ox.ac.uk/alois), the specialised register of the Cochrane Dementia and Cognitive Improvement Group (CDCIG). We ran additional searches in MEDLINE, Embase, PsycINFO, CINAHL, ClinicalTrials.gov, and the WHO Portal/ICTRP at www.apps.who.int/trialsearch, to ensure that the search was as comprehensive and as up-to-date as possible, to identify published, unpublished, and ongoing trials. SELECTION CRITERIA We included randomised controlled trials (RCTs) or quasi-RCTs, published or unpublished, reported in any language. Participants were cognitively healthy people between 40 and 65 years of age (80% of study population within this age range). Experimental interventions adhered to the following criteria: intervention was any form of interactive computerised cognitive intervention - including computer exercises, computer games, mobile devices, gaming console, and virtual reality - that involved repeated practice on standardised exercises of specified cognitive domain(s) for the purpose of enhancing cognitive function; duration of the intervention was at least 12 weeks; cognitive outcomes were measured; and cognitive training interventions were compared with active or inactive control interventions. DATA COLLECTION AND ANALYSIS For preliminary screening of search results, we used a 'crowd' method to identify RCTs. At least two review authors working independently screened remaining citations against inclusion criteria; independently extracted data; and assessed the quality of the included trial, using the Cochrane risk of bias assessment tool. We used GRADE to describe the overall quality of the evidence. MAIN RESULTS We identified one eligible study that examined the effect of computerised cognitive training (CCT) in 6742 participants over 50 years of age, with training and follow-up duration of six months. We considered the study to be at high risk of attrition bias and the overall quality of the evidence to be low.Researchers provided no data on our primary outcome. Results indicate that there may be a small advantage for the CCT group for executive function (mean difference (MD) -1.57, 95% confidence interval (CI) -1.85 to -1.29; participants = 3994; low-quality evidence) and a very small advantage for the control group for working memory (MD 0.09, 95% CI 0.03 to 0.15; participants = 5831; low-quality evidence). The intervention may have had little or no effect on episodic memory (MD -0.03, 95% CI -0.10 to 0.04; participants = 3090; low-quality evidence). AUTHORS' CONCLUSIONS We found low-quality evidence from only one study. We are unable to determine whether computerised cognitive training is effective in maintaining global cognitive function among healthy adults in midlife. We strongly recommend that high-quality studies be undertaken to investigate the effectiveness and acceptability of cognitive training in midlife, using interventions that last long enough that they may have enduring effects on cognitive and brain reserve, and with investigators following up long enough to assess effects on clinically important outcomes in later life.

Abstract
BACKGROUND The number of people living with dementia is increasing rapidly. Clinical dementia does not develop suddenly, but rather is preceded by a period of cognitive decline beyond normal age-related change. People at this intermediate stage between normal cognitive function and clinical dementia are often described as having mild cognitive impairment (MCI). Considerable research and clinical efforts have been directed toward finding disease-modifying interventions that may prevent or delay progression from MCI to clinical dementia. OBJECTIVES To evaluate the effects of at least 12 weeks of computerised cognitive training (CCT) on maintaining or improving cognitive function and preventing dementia in people with mild cognitive impairment. SEARCH METHODS We searched to 31 May 2018 in ALOIS (www.medicine.ox.ac.uk/alois) and ran additional searches in MEDLINE, Embase, PsycINFO, CINAHL, ClinicalTrials.gov, and the WHO portal/ICTRP (www.apps.who.int/trialsearch) to identify published, unpublished, and ongoing trials. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs in which cognitive training via interactive computerised technology was compared with an active or inactive control intervention. Experimental computerised cognitive training (CCT) interventions had to adhere to the following criteria: minimum intervention duration of 12 weeks; any form of interactive computerised cognitive training, including computer exercises, computer games, mobile devices, gaming console, and virtual reality. Participants were adults with a diagnosis of mild cognitive impairment (MCI) or mild neurocognitive disorder (MND), or otherwise at high risk of cognitive decline. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed risk of bias of the included RCTs. We expressed treatment effects as mean differences (MDs) or standardised mean differences (SMDs) for continuous outcomes and as risk ratios (RRs) for dichotomous outcomes. We used the GRADE approach to describe the overall quality of evidence for each outcome. MAIN RESULTS Eight RCTs with a total of 660 participants met review inclusion criteria. Duration of the included trials varied from 12 weeks to 18 months. Only one trial used an inactive control. Most studies were at unclear or high risk of bias in several domains. Overall, our ability to draw conclusions was hampered by very low-quality evidence. Almost all results were very imprecise; there were also problems related to risk of bias, inconsistency between trials, and indirectness of the evidence.No trial provided data on incident dementia. For comparisons of CCT with both active and inactive controls, the quality of evidence on our other primary outcome of global cognitive function immediately after the intervention period was very low. Therefore, we were unable to draw any conclusions about this outcome.Due to very low quality of evidence, we were also unable to determine whether there was any effect of CCT compared to active control on our secondary outcomes of episodic memory, working memory, executive function, depression, functional performance, and mortality. We found low-quality evidence suggesting that there is probably no effect on speed of processing (SMD 0.20, 95% confidence interval (CI) -0.16 to 0.56; 2 studies; 119 participants), verbal fluency (SMD -0.16, 95% CI -0.76 to 0.44; 3 studies; 150 participants), or quality of life (mean difference (MD) 0.40, 95% CI -1.85 to 2.65; 1 study; 19 participants).When CCT was compared with inactive control, we obtained data on five secondary outcomes, including episodic memory, executive function, verbal fluency, depression, and functional performance. We found very low-quality evidence; therefore, we were unable to draw any conclusions about these outcomes. AUTHORS' CONCLUSIONS Currently available evidence does not allow us to determine whether or not computerised cognitive training will prevent clinical dementia or improve or maintain cognitive function in those who already have evidence of cognitive impairment. Small numbers of trials, small samples, risk of bias, inconsistency between trials, and highly imprecise results mean that it is not possible to derive any implications for clinical practice, despite some observed large effect sizes from individual studies. Direct adverse events are unlikely to occur, although the time and sometimes the money involved in computerised cognitive training programmes may represent significant burdens. Further research is necessary and should concentrate on improving methodological rigour, selecting suitable outcomes measures, and assessing generalisability and persistence of any effects. Trials with long-term follow-up are needed to determine the potential of this intervention to reduce the risk of dementia.

Abstract
Ventricular septal defect (VSD) is a rare, potentially fatal complication of acute myocardial infarction. When surgical closure is contraindicated, transcatheter closure may be an alternative. Residual shunting after transcatheter closure of postinfarction VSDs has been reported; however, we found few cases of this in patients who also had severe heart failure or hemolysis. We report 2 closures of postinfarction VSDs with use of the Amplatzer Septal Occluder. Both elderly patients-one with severe heart failure, one with persistent hemolysis, and neither a surgical candidate-had high-velocity residual shunting through the occluders. We intensively managed the patients' conditions and used angiography and transthoracic echocardiography to record the gradual disappearance of each shunt over 4 months-the first such serial monitoring of which we are aware. We think that even substantial shunting in the presence of severe heart failure or hemolysis can eventually resolve spontaneously, assuming effective management of the concomitant medical conditions.

Abstract
Infrarenal abdominal aortic aneurysm with aortocaval fistula, a rare condition, can be fatal without prompt intervention. The clinical symptoms are complex and varied, so diagnosis is typically confirmed by use of contrast-enhanced multidetector computed tomography. We report our surgical repair of a 13-cm-diameter infrarenal abdominal aortic aneurysm and aortocaval fistula in a 63-year-old orchestral tuba player who had 2 classic symptoms of the condition. The unruptured aneurysm and fistula were complicated by acutely angled vessels, so we performed surgery rather than endovascular repair. The patient recovered fully and was discharged from the hospital. This infrarenal aneurysm with aortocaval fistula is perhaps the largest to have been treated successfully by means of open surgery. In addition to our patient's case, we discuss the history and treatment considerations of this rare combined condition.

Abstract
BACKGROUND Preterm infants have low plasma levels of erythropoietin (EPO), providing a rationale for the use of erythropoiesis-stimulating agents (ESAs) to prevent or treat anaemia. Darbepoetin (Darbe) and EPO are currently available ESAs. OBJECTIVES To assess the effectiveness and safety of late initiation of ESAs, between eight and 28 days after birth, in reducing the use of red blood cell (RBC) transfusions in preterm or low birth weight infants. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL 2018, Issue 5), MEDLINE via PubMed (1966 to 5 June 2018), Embase (1980 to 5 June 2018), and CINAHL (1982 to 5 June 2018). We searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA Randomised or quasi-randomised controlled trials of late initiation of EPO treatment (started at ≥ eight days of age) versus placebo or no intervention in preterm (< 37 weeks) or low birth weight (< 2500 grams) neonates. DATA COLLECTION AND ANALYSIS We performed data collection and analyses in accordance with the methods of the Cochrane Neonatal Review Group. We used the GRADE approach to assess the quality of the evidence. MAIN RESULTS We include 31 studies (32 comparisons) randomising 1651 preterm infants. Literature searches in 2018 identified one new study for inclusion. No new on-going trials were identified and no studies used darbepoetin.Most included trials were of small sample size. The meta-analysis showed a significant effect on the use of one or more RBC transfusions (21 studies (n = 1202); typical risk ratio (RR) 0.72, 95% confidence interval (CI) 0.65 to 0.79; typical risk difference (RD) -0.17, 95% CI -0.22 to -0.12; typical number needed to treat for an additional beneficial outcome (NNTB) 6, 95% CI 5 to 8). There was moderate heterogeneity for this outcome (RR I² = 66%; RD I² = 58%). The quality of the evidence was very low. We obtained similar results in secondary analyses based on different combinations of high/low doses of EPO and iron supplementation. There was no significant reduction in the total volume (mL/kg) of blood transfused per infant (typical mean difference (MD) -1.6 mL/kg, 95% CI -5.8 to 2.6); 5 studies, 197 infants). There was high heterogeneity for this outcome (I² = 92%). There was a significant reduction in the number of transfusions per infant (11 studies enrolling 817 infants; typical MD -0.22, 95% CI -0.38 to -0.06). There was high heterogeneity for this outcome (I² = 94%).Three studies including 404 infants reported on retinopathy of prematurity (ROP) (all stages or stage not reported), with a typical RR 1.27 (95% CI 0.99 to 1.64) and a typical RD of 0.09 (95% CI -0.00 to 0.18). There was high heterogeneity for this outcome for both RR (I² = 83%) and RD (I² = 82%). The quality of the evidence was very low.Three trials enrolling 442 infants reported on ROP (stage ≥ 3). The typical RR was 1.73 (95% CI 0.92 to 3.24) and the typical RD was 0.05 (95% CI -0.01 to 0.10). There was no heterogeneity for this outcome for RR (I² = 18%) but high heterogeneity for RD (I² = 79%). The quality of the evidence was very low.There were no significant differences in other clinical outcomes including mortality and necrotising enterocolitis. For the outcomes of mortality and necrotising enterocolitis, the quality of the evidence was moderate. Long-term neurodevelopmental outcomes were not reported. AUTHORS' CONCLUSIONS Late administration of EPO reduces the use of one or more RBC transfusions, the number of RBC transfusions per infant (< 1 transfusion per infant) but not the total volume (mL/kg) of RBCs transfused per infant. Any donor exposure is likely not avoided as most studies included infants who had received RBC transfusions prior to trial entry. Late EPO does not significantly reduce or increase any clinically important adverse outcomes except for a trend in increased risk for ROP. Further research of the use of late EPO treatment, to prevent donor exposure, is not indicated. Research efforts should focus on limiting donor exposure during the first few days of life in sick neonates, when RBC requirements are most likely to be required and cannot be prevented by late EPO treatment. The use of satellite packs (dividing one unit of donor blood into many smaller aliquots) may reduce donor exposure.
